Detect current CPU Clock Speed Programmatically on OS X?

macos cpu clock cpu-speed

I just bought a nifty MBA 13" Core i7. I'm told the CPU speed varies automatically, and pretty wildly, too. I'd really like to be able to monitor this with a simple app.

Are there any Cocoa or C calls to find the current clock speed, without actually affecting it?

Edit: I'm OK with answers using Terminal calls, as well as programmatic.

Thanks!
